INIPRVEMENT IN PUDDLINGFURNACE DOORS.

Specification forming part of Letters Patent No. 140,730, dated July 8,1873; application filed April 11, 1813.

y.To all whom it may concern:

Be it known that I, J oHN S. BEES, of Phillipsburg, in the county ofWarren and'in the State of New Jersey, have invented certain new anduseful Improvements in NVater- Frame and Door for Paddling and HeatingFurnaces; and do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the accompanyingdrawings and to the letters of reference marked thereon making a part ofthis specification. y

The nature of my invention consists in the construction and arrangementof a door-frame and door for puddling and other furnaces, as will behereinafter more fully set forth. y

In order to enable others skilled in the art to-w-hich my inventionappertains to make and use .the same, I will now proceed to describe itsconstruction and oper-ation, referring to the annexed draw-ing, inwhich- Figure 1 is afront elevation, and Fig. 2 `is a plan View of myframe and door.

A represents the door-frame, and B the sliding door of a puddling orother furnace.` The frame A contains within it a tube, C, which may bebent and fitted to different shapes and forms. a represents the inlet tosaid pipe G, through which the water is admitted, and b is the outletconnected, by asliding joint, d, or rubber or other hose, with awater-tube, D, contained within the door B, and also bent and fitted inany desired shape and form.

Each tube may be one continuous piece, or made with elbows; but it willbe more dura ble if made of one piece of pipe. In case of low water thepipe will not crack; or if the water is stopped and the tubing becomesredhot a stream of water put into the pipes will not crack them as itwill cast-iron.- Again,

the tubular frame is better because the water has a direct course by thepoints most exposed to the fire, and may be guided wherever the buildermay wish. By the use of the tubular frame there will be no overlow ofWater, for

` Water-tube C, can be cast in two parts, so that if the front half beremoved it will .expose to View the pipes, while the inside half willremain to keep the brick-work in place, and will also keep the tubing inposition. The parts when put together are fastened with screws or bolts;or the whole door-frame may be cast solid, with the tubing in the centeras a core; or the tubing may be used without the castiron frame, and maybe placed in the brick walls. 'lhe lugs j' f on the bottom of lthe frameform a rest for the brick-work inside.

The door B with its water-tube D may be made precisely in the samemanner as described for the frame A, but the brick-work in the door ismade in one, so that it can be taken out and replaced-ina few minutes,while furnace is being worked. 0n the frame A are adjustable dovetailguides GG, in which the door works, which are of great importance to theframe, with or without the water. The dovetail keeps the door in itsproper place, and will protect the tubing when taking iron from thefurnace. The guides are adjusted by means of bolts 71. h passing throughslots i in the guides, whereby the door may be kept tight and stationaryin ,any position the worker may desire, and .dispenses with the use oflugs, pins, and bars, now so generally used.

At the lower edge of the door B is an aperture, m, closed by astoppcr,H. This stopper is arranged to slide in dovetailed guides n n, andremains on the door; and it is held up by a spring, I, while working theiron and while taking the iron fromv the furnace, instead of taking thestopper orf. i

Having thus fullydescribed my invention, what I claim as new, anddesireto secure by Letters Patent, is-

1. vThe combination of the frame A, door B,

and adjustable guides Gr Gr, substantially as and for the purposesherein set forth.

2. The combination of the door B, stopper H, and spring I, substantiallyas and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this14th day of March, 1873. p
